United States Secretary of State Hillary "We came, we saw, he died" Clinton's message to Pakistan was stark; try to go ahead with the IP (Iran-Pakistan) gas pipeline, and we're going to take you out financially.
Islamabad, its economy in tatters, living in power-cut land, and desperate for energy, tried to argue. Pakistan's top official in the Petroleum and Natural Resources Ministry, Muhammad Ejaz Chaudhry, stressed that the 2,775-km, $1.5 billion IP was absolutely crucial for Pakistan's energy security.
That fell on deaf ears. Clinton evoked "particularly damaging" sanctions - tied to Washington's push to isolate Iran by all means available and the no-holds-barred campaign to force particularly India, China and Turkey to cut off their imports of Iranian oil and gas.
So as Washington has been impotent to disrupt Pipelineistan moves in Central Asia - by isolating Iran and bypassing Russia - it's now going ballistic to prevent by all means the crucial integration of Southwest Asia and South Asia, from Iran's giant South Pars gas field to Pakistan's Balochistan and Sindh provinces.
To compound Washington's fury, "isolated" Iran, by the way, is about to start exporting an extra 80,000 barrels of oil a day to Pakistan; and has already committed $250 million to the Pakistani stretch of IP.
This has got the potential of becoming much, much uglier. Washington won't be deterred from its intent to smash IP. For an Iran under pressure and a strangled Pakistani economy - as well as China - this is all about the Asian Energy Security Grid.
